<p><P>PROBLEM TO BE SOLVED: To provide an exhaust system for a diesel engine by which combustible gas in an exhaust passage can be burned reliably. <P>SOLUTION: The exhaust system for a diesel engine is provided with a gas generator 3 including a catalyst chamber 51. A catalyst 4 is held in the catalyst chamber 51 wherein catalytic combustion heat is evolved. The catalyst chamber 51 is provided along a peripheral wall 1a in the exhaust passage. The peripheral wall 1a along which the catalyst chamber 51 is arranged serves as a heat radiation wall 8. While combustible gas 7 and exhaust gas 10 heated in the catalyst chamber 51 are being mixed in the exhaust-gas passage 1, catalytic combustion heat evolved in the catalyst chamber 51 is radiated onto the mixture gas from the heat radiation wall 8 so as to ignite the combustible gas 7 with the heat-radiating wall 8 serving as ignition means 45. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
